As I understand, just a little over 400 million funding will come from Monumental Sports & Entertainment, and the rest of the 2 billion from the state of Virginia. The DC city council had a last ditch offer last night of 500 million, probably just to save face.
The Caps moving out of Metro Center/Chinatown will completely destroy what's left of that area. Pretty much all of the business in that area was supported by office workers who never came back after COVID, and the Capital One Area. Right now it's basically a open-air drug market, riddled with theft and vandalism similar to pockets in San Francisco. Outside of Caps games, I wouldn't recommend anyone walk around there.
With how incompetent DC Council is, it won't be too long before DC is a suburb of NoVa.
